Application filed May 4, 1917. Serial No. 166,4:47.

bodies among other features a longitudi nally disposedpartition dividing the smoke box into separate compartments, and serving to confine the products of combustion in the lowermost compartment an appreciable length of time, with a view of destroying.

the sparks in this compartment, and thus preventing the passing of the same into the atmosphere through the other compartment and smoke stack, which quite frequently causes damage to adjacent buildings by fire.

erence indicate similar parts in the several In carrying out my invention I provide means whereby the partition is firmly. supported within the smoke stack but susceptible of beingremoved therefrom to be cleaned, or for any other purpose as the occasion may require.

The nature and advantages of the invention will be better understood when the 01 lowing detail description is read inI connection with the accompanying drawing, the invention residing in the construction, com bmation and arrangement of parts I as claimed. e e e e e In the drawing forming part of this specification and wherein like numeralsof refviews v I v Figure 1 1s a horlzontal sectional view through the smoke box of a locomotive showing the invention.

Fig. 2 is a vertical longitudinal sectional view therethrough.

Fig. 3 is a vertical transverse sectional view, taken on line 33 of Fig. 2.

Referring more particularly to the draw- I ing IOindicates the smoke box of a locomotive boiler, which may be of any preferred construction, provided with the usual smoke stack 11 and door 12. Arranged within the smoke box at diametrically opposite polnts are spaced longitudinally extending cleats 13, each pair of the latter defining guides for the horizontally disposedIpartition 14. The latter is coextensive in length the apertures 'disposedin the vicinity of that part ofthe partition underthe smoke stack, wherethe strongest draft occurs, be ing much smaller than the remaining aperwith the length of the smoke box and is provided with a plurality of apertures 15,

tures. If desired the partition maybe also provided with a nozzle 16 which is disposed lmmediately beneathand in a line with the 1 smoke stack 11, the nozzle having a restricted boreIand outlet. The partition is disposed slightly above the fire tubes 17, and it is manifest that the products of combustion are introduced into the smoke box beneath the partition1l wwhich latter confines the smoke and other products of combustion within the space beneath I the partition an appreciable length of time, with a view or destroying the sparks, and thus preventing the latter from escaping from thesmoke box I through thestack 11 to the atmosphere.

Extending transversely of the smoke box are bars 18 having their upper surfaces lying flush with the corresponding surfaces of the lowermost cleats 13, so that thelpartition It will rest upon the bars and be thereby firmly supported within the smokebox. However the construction and arrangement is such that the partition 14 can be readilyand easily withdrawn ,from the smoke box through theforward endthereof, subsequent to the opening of the door 12, when it is.

desired toclean the partition, to replace the same by a new one, or for any other purpose as the occasion may require going description the nature andadvantages of the inventionwillwbereadilyapparent,

What is claimed is I In combination with thesmoke box of a e0 While: it is believed that fromthe fore locomotive boiler having a stack, a spark neath the stack being of considerably less arrester comprising a horizontally disposed diameter than the remaining holes whereby partition plate slidably arranged Within the the draft at its area of maximum strength 10 smoke box and extending entirely across subwill be materially retarded.
